This crankset was purchased to replace an aging 8 spd setup on my TREK carbon bike. It is used mostly for winter training, however I wanted something I could ride in the spring and fall when the mountain bike trails were not accessible. It was easy to install, however I found little information on correct BB spindle lengths and went a couple of mm's shorter. The same spindle length between the ISIS and square taper BB's do not provide the same chainline, and I did have some adjustments to make on the front derailleur. It seemed to be as light as my old 8 speed Ultegra, however I did not weigh it. It looks great on my all black carbon bike, and on my initial 30 mile ride I had no issues with shifting from the small to the large ring and back. Combined with a new chain and cassette, I now have the benefit of compact gearing to help with all the climbing in my area. Considering the price, looks and function, it is perfect for updating an older bike.

A workhorse crankset that shifts as good as most mid to high level compact cranks I see in other club member bikes. No the rings aren't as stiff as Dura Ace, Red or Record, but if your in the market for those you wouldn't buy this crank to begin with. The chainrings won't shift as well as the $120 dollar rings available for pros, nor are the cranks as light as top end cranks. ISIS is not as solid a stiff a system as the external BB nor is it as durable as old square taper systems. ISIS is a common spec and the BBs are readily available. This considered, you might need a new bottom bracket every 5000 Miles and the weight might cost a pro 30 seconds over the course of 50 miles, but this crank is an excellent buy for most us. It is very inexpensive, less expensive than shimano Claris for everything, and just plain works. It shifts as good as 105 and older Ultegra level cranks I've seen, and is usable on any frame with a threaded BB. It deosn't replace a standard crank where they excel, nor does it replace a triple for places where triples shine, but for the typical road bike this VALUE is hard to beat. I used the one I purchased with NOS Sora 3300 and Tourney shifters and it works well. No problems whatsoever. I imagine it would even better with higher end groupsets.

I am at the age where I need to reduce my gears to save my knees. This compact crank is great at the price. Everything else was much more expensive. The weight was about the same as stuff twice the price. I can not detect any more flex than the Dura Ace crank (20 years old) this replaced.

I bought my first CR2 and installed it on a black with silver lettering CAAD5, in place of the Centaur triple. The running around/errands bike. The black/silver trim of the crank makes the old Cannondale look better. With a 13-29 I get the same lowest gear as the triple without all the shifting. Love this crankset! I then bought a second CR2 and installed it on a carbon bike that was mainly Chorus w/ a carbon crankset 39/53. Plenty of black on this bike, too, especially the ROL wheels. The alloy CR2 actually looks better than the carbon sq. taper Chorus it replaced.I am old and slow, so I can use the low gears a compact has. Looks good; rides good. Nothing about this crankset I don't like. If Nashbar offered it in silver, I'd put one on another bike, too.

No, this isn't state of the art so don't expect light weight and sexy (beer budget doesn't equal champagne performance, get real). For a commuter bike, winter road bike, or casual roadie though, this simply does the job. Some carb cleaner on a rag gets rid of the (IMHO) cheesy pin stripes on the arms and the good old black permanent marker (great for touching up scratches on black parts!) took care of the Nashbar "N" on the big ring - presto! basic black, solid performer.

This crankset paired with the Nashbar ISIS Bottom Bracket (Item #NS-ISBB-68X108) looks nice, went on smoothly. I expected a nice product and smooth installation and was not disappointed. Durability has yet to be tested, but it sure LOOKS like there should be no issue there. The serious racers will likely look for something lighter / flashier.NOTE: (Make sure you use Park Tool BBT-22C Bottom Bracket Tool (Item #PT-BBT22C) or equivalent - my older Park BBT-2 tool will NOT fit over the large diameter ISIS BB's hollow axle - I learned that with my last ISIS BB purchase / installation.
